BUMPER ATTACHMENT Filed Sept. 5, 1933 faz/emga Patented May 26, 1936 UNITED STATES 4PATENT Y OFFICE 2,041,931 BUMPER ATTAcnMENT Adolph Hunziker, Jr., chicago, 1u.' l Application September 5, 1933, Serial No. 688,091 1o ola-ms.Y (crease-55) My invention'relates to improvements in attachments for automobile bumpers or the like andhas as its principal object the production of a prong or stud which may be readily applied to the bumper bar, a plurality or series ofthe devices being ordinarily applied and spaced the desired distance apart. The purpose of said devices is primarily to provide a series of prongs or studs on the rear bumper bar which will render the bumper inconvenient and uncomfortable for use as a support for a person who may desire to stand or sit on the same. The present invention is in the nature of an improvement over the device shown in my pending applica- `1li tion, Serial No. 631,880.

The invention has among its objects the production of a device of the kind described'which is simple, eiiicient, attractive, inexpensive and satisfactory as a safety device for the purposes 2U set forth. The device has also as an object the production of a device which may be readily attached without tools other than a screw driver or the like, it being possible to provide as many or as few of the unitary devices to the bumper as may be found necessary or desirable. A further object is the production of a safety device which will be ornamental and attractive and embellish the bumper, as well as add to the safety.

Many other objects and advantages of the construction herein shown and described will be obvious to those skilled in the art from the disclosure herein given. n

To this end my invention consists in the novel construction, arrangement and combination of parts herein shown and described, and more particularly pointed out in the claims.

In the drawing, wherein like reference characters indicate like or corresponding parts:`

. Fig. 1 is a view in elevation showing the device applied to a bumper bar;

Fig. 2 is a sectional view taken substantially on line 2-.-2 of Fig. 1; and

Fig. 3 is a perspective view showing` the opposite side to that shown in Fig. 1.

Referring to the drawing, it may be mentioned that I provide a plurality of devices each of which is a unitary structure in itself which may be applied to the bumper bar, as many or as few of the devices being employed as may be desired. 50 oniy one device is shown in the drawing. As

shown, I represents a portion of a car bumper bar, the rear or exposed face of the same being shown in Fig. 1, as ordinarily the safety devices areemployedonly on the rear bumper of an au- 55 tomobile. Any vehicle, however, having a bumper may be equipped with the devices. As shown, the device substantially consists of a top member designated generally as II, which is mounted on the top edge of the bumper bar, a cooperating securingwmember generally designated as I9 which engages the lower edge of the bar and interconnecting means between the parts II and I9, said interconnecting means being adjustable to permit the device to be: readily fastened to bumper bars of different sizes. The member II 10 is made up of a plate part I3 which is arranged to seat'upon the top edge of the bumper bar and which carries an upstanding prong or stud I2 which terminates in a reduced portion or point at the top. The plate I3 is shown with depend- 15 ing lugs or tongues I4 and I5 which overlie the two faces of the bumper bar and maintain the plate I3 from moving transversely of the bar. As shown, lug I5 is provided with a laterally extending flange I6, it being immaterial as to 20 whether the ilange IS is formed integrally with I5 or attached thereto. As most clearly shown in Figs. 2 and 3, the same is formed as a part of the brace member I'i which may be secured to part I5 by a rivet I8 or equivalent means. 25

The cooperating member I9 consists of a portion 20 which underlies the lower edge of the bumper bar and the adjacent portions 2I and 22 which overlie the front and back faces of the bar, the sameV constituting substantially a 30 hook for engaging the lower edge of the bar of the bumper. A flange 23 is provided which eX- tends adjacent or substantially inv alignment with the flange I6. The two anges are connected by means of a bolt 24 and nut 25 or equivalent means. When the parts are seated on the edges of the bar as shown in the figures and the nut 25 tightened down on the bolt, the device is securely and firmly locked on the bumper bar.

To stiffen and make the device more attractive 40 the prong I2 may be provided with flanges 26 and 21 at ,the sides which may be folded over and brought together at their meeting edges as indicated at 28 and the two edges brazed, spot welded or otherwise secured together. The stud or prong in the design of a pyramid is pleasing in appearance as well as rigid. To support and brace the two sides 2t and 2'I the part I1 may be extended up as indicated at 29 and secured to the two sides, thereby reenforcing the head and preventing bending over of the prong I2. It will be noted, however, that the bottom edges of the anges 26 and 2'I rest directly on the bumper bar so that regardless of the brace 29 the side anges brace and reenforce the prong I2. While the side flanges are not strictly essential, they do add to the appearance and perform the bracing function mentioned, as well as permit the use of lighter material without danger of the bending down of the stud.

The devices are ordinarily stamped out of metal of suitable gauge, as for example sheet steel,

referably a stainless steel, or of any other suitable material which may be plated. Devices made as described lend themselves to application on bumpers and bumperettes of various types or shapes and sizes, it being possible to purchase just the number required to properly equip the bar to the bumper and to apply them with only a screw driver as a tool. Obviously, a child or adult standing or sitting on the bumper bar equipped with these devices would find the same extremely uncomfortable. Many accidents result from this practice and these devices are intended to prevent the unauthorized riding on the bumper.

Having thus described my invention, it is obvious that various immaterial modifications may be made in the same without departing from the spirit of my invention; hence, I do not Wish t be understood as limiting myself to the exact form, construction, arrangement and combination of partsA herein shown and described, or uses mentioned.

What I claim as new and desire to secure by Letters Patent is:
